[0002] In the existing winding skeleton, the winding layer of the skeleton is a plastic layer structure. When the coil is energized and heats up to a certain temperature, the nylon material will start to melt. At this time, the copper wire is easily embedded in the nylon material, and the embedded copper wire is more stable. It is difficult to dissipate heat, which will form a vicious circle, and the coil temperature will eventually be burned if it cannot be dissipated

The invention discloses a winding framework, which comprises a framework upper plate, a framework winding layer, an inner bush and a framework lower plate, wherein the framework winding layer is of a paper pipe structure, and a split type structure is arranged among the framework upper layer, the framework winding layer and the framework lower plate; an upper hole size and a lower hole size which are matched with the inner bush are respectively arranged on the framework upper plate and the framework lower plate, and the inner bush is nested into the upper hole and the lower hole; an outwardly turned edge is arranged on the upper port of the inner bush and is matched with the upper hole of the framework upper plate and limited by the upper hole, and an upper notch and a lower notch are respectively arranged in the openings of the upper hole and the lower hole; and the framework winding layer is arranged between the framework upper plate and the framework lower plate, and an iron framework pressing ring is arranged on an outer ring of an inner bush part exposed from the framework lower plate. The winding framework has the advantages of good heat resistance and heat dissipation performance, low production cost, and firmness and reliability, and does not easily swell after being wound, the magnetoconductivity is increased when the winding framework is installed, and the product performance is improved.
Description
technical field [0001] The invention relates to a winding frame for coil winding. Background technique [0002] In the existing winding skeleton, the winding layer of the skeleton is a plastic layer structure. When the coil is energized and heats up to a certain temperature, the nylon material will start to melt. At this time, the copper wire is easily embedded in the nylon material, and the embedded copper wire is more stable. It is difficult to dissipate heat, which will form a vicious circle, and the coil temperature will eventually be burned if it cannot be dissipated. Contents of the invention [0003] The purpose of the present invention is to provide a winding skeleton with good temperature resistance, low cost, simple mold making and good product performance in order to solve the above-mentioned deficiencies in the prior art. [0004] In order to achieve the above object, a winding skeleton designed by the present invention includes a skeleton upper layer, a skele...
